What is the mechanical advantage of a screw with a pitch of 0.05 inches and a head with a diameter of 0.30 inches if you turn it with a screwdriver whose diameter is 1.5 inches? I think the equation to solve this would be:

Circumference witch is equal to 3.1416 x the Diameter witch is 1.5 inch. ÷ by the pitch witch is 0.05 inch.

S... the answer would be 94.248?

Correct me if i'm wrong because i really don't know.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

the answer is:

mean: 6

mad: 2.14

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
